NOTE: This list is about mostly non-sentient creatures of natural, alien or scientific origin running amok. Since ""creature feature"" is in a way a sub-genre of science fiction, supernatural beasties need not apply. As usual, only theatrical releases, i.e. movies that actually have box office grosses to their names, are counted. That's important to note here as most ""creature features"" go straight to video or cable. If there are any movies that you think should be on this list, e-mail us at mail@boxofficemojo.com.
